You cannot import AC5300 setting into AX-11000. You need to start to setup your AX11000 from scratch. Once you set your AX11000 router, hard reset your AC5300 to factory default setting. Now you can either hard wired your AC5300 or wireless connect as a mesh. Go to the AI mesh tab on your AX11000 admin page start to add the AC5300 to form a mesh connection. Hope this will help you. Good day.
